fails if library has main()

I need to link against a library (/usr/lib/libf2c.a)
that includes a definition of main().  When I try to
link a program (ghc ... -lf2c), it uses the definition
of main() from that library.

The workaround is to link with -lHSrts -lf2c.

This should at least be documented (with a description
of the workaround), if not fixed.

(Let me know if you need a full test case, reproduction
scenario, etc.)

The ability to use your own main() is a feature, not a 
bug.  But anyway I've documented this particular gotcha in 
the description of the -l flag in the user's guide.
